The Effects of Stimulants on Invertebrates: Caffeine and Dietary Supplements
ثبت نشده
چکیده
Caffeine and dietary supplements have been shown to play a role in the regulation and circulation of blood. If taken in excessive amounts, they may cause damage to the circulatory system or heart. To test the effects for myself, I administered both caffeine and dietary supplements on water organisms, specifically daphnia. The results for caffeine turned out as expected and further proved the effects of caffeine. For dietary supplements, the unexpected results showed that dietary supplements cause irregularity in heart rate. There was a very clear jump in daphnia heart rate between 30–60mins. for both stimulants. Sometimes, the heart rate would almost double when exposed to caffeine. With dietary supplements, there was dramatic inconsistency in the heart rate. The effect of dietary supplements on the daphnia’s heart rate was that it made the heart rate irregular and undependable. One might never know what might happen under the influence of dietary supplements.
